- To all whom t may concern.'

Be it known that I, AIM- BOULANGER, a. subject of the King ofGreatBritain, residing at Normandin, Province of Quebec, 5 Canada, haveinvented certain new and useful Improvements in Hoisting Devices; and ldo hereby declare that the following isf a ful-l, clear,` andexactgdes'cription ofthe invention, such as will enable others skilledin the art to which it 'appertains to make and use thesa'me.y

The present invention pertainsto novel; improvements in a hoistingdevice designed particularly for use on farms. l

The primary objecty of theinvention is the provision of va-'device ofkythis character including a winding'drum', the direction of rotation ofwhich may bef reversed at will. Qbviously, the; drum isl turned inthe'windingv direction to raise'the; lo'ad, and in the; op-

positedirection to allow the-'descent ofthe' free unweighted en-dof th'ecable after? they load has,` been renrio-ved' therefrom? 'lhe inventionyfurther includesA a braking' mechanism for'` preventingfrotation ofthe'drum in case the fengineish'ould stop; at an-- undesired time. Becauseofv the fact. that-- gas engines whichf arey used onfarming implementsare likelyto stop at an unexpected moment, th-isf bralring dev-icel isyuseful,v in@ preventing load in the unexpectedly. l 1 The inventionFisfully-disclosed in thefo'llowing description and ir thel accompanyingdrawings inawhiclr: Y

Figure 7 is a-section on the line 7-.7'.ofK Figure 6. l D The deviceycomprises ai base 11'onwhiclfiis'A mounted a gasolineengine2including acyl; inder 3. The' engine c'asing includes-V apair of vertical members'4" the' tops of ywhich are tted with bearings .for supportingfinr arotatable manner the crankshaft 6.v The the descent off a: partlyraisedevent that the engine shouldsto-p latter is connected to thepiston (not shown) ofthe engine by means of a connecting rod 7 intheusuagl manner. v

On the ends of the crank shaft are mounted ily wheels 8 and 9, the endadjacent the 'wheel 8 having an extension 10 through which is passed apin 11. On this end is slidably receiveda driving pulley 12 on the innerface lof which is formed a boss 13 having a Vtransverse slot 14 adaptedto receive the pin 11. A ystem 15 extends from the outer face of thepulley and has formed thereon a p'air of spaced collarsV 16. A bracket17 is secured to the base in a line beneath the extension 10 and stem15, and vhas pivoted thereto a shifting lever 18 which straddles thestem between the collars 16 in' such a manner that the pulley 12 can bemoved upon actuation of the lever.

On the base 1, forward of the side members fi 'are mounted a. pair ofblocks 19 and 20,-` one end of a counter shaft 21 being jour#nalled'inthe' block 19. A be'aringblock 22 havingv elongated verticalslots 23 formed therethrough is slidably mounted on the block 2O bymeans of boltsv 24 passing thjrough thel slots and| extending into theblock. `Theother end of; the counter shaft 21*isfjournalled intheslidable block` 22. On onejendf of the countershaft iskeyeda drivenpulley 25 in alignment with the driver 12, a belt 26 beingnsed fortransmitting power from the driving; to the driven pulley'. At theopposite end of the counter shaft isV mounted an auxiliary pulley 27- inalignment with the fly wheel 9. Ac lever 28' has its intermediateportion connected to the lcounter shafft 21, as shbwnin Figure 1,- thelower end being pivoted to the base` 1,: as indicated by the numeral 29.intermediate the pulleys 9 25- and 27 ,f al drum 30 is xed tothe countershaft,y having av hoisting cable' 3-'1 wound therearound;

In operation, the auxiliary pulley 27 is normally held out of engagementwith the fly wheel' 9", asv shown in Figures 1 and 2. The' pulley 12 isshifted inwardly so that the pin 11 is received in the slot 14, wherebythe pulley 12 is rotated with the crank shaft and transmits' power tothe driven pulley 25 and' through the belt 26. The' oranlrshaft turningi'nat clockwise direction consequently causes the drum to rotateinthesame direction whereby they cable 31- is wound thereon. Inf thisposition the device can' obslidably mounted on said end vand having a.

viously be used for hoisting the cable being nierelytrained over apulley fixed to an ele-l vated support.

At the end of a hoisting operation, after the load has been removed fromthe end of the cable, the weight of the latter even when combined withthe grapple is insufficientv to lower the same.v Accordingly, theshifting device 18 is pulled outwardly sothatfthe pulley l2 i-sfreedfrom the pin 11 and no power isvtransinitted therefrom to thedrum.l

The lever 28 is now pushedy rearwardly, bringing the auxiliary pulley'27 into engagement with the Hy wheel)V whereby the drum is rotated vin acounter" clockwise direction allowing the free end ofthe cable vtodescend.

To the inner face lof the block 20 is pivoted a brake lever .33 adaptedfor engagement with the auxiliary pulleyl 27. Inasy muchas this deviceis adapted for use on farms where gas engines are generally employed, itis very likely that the engine will stop in the midst of av hoistingoperation.v In the event that such an occurrance takes place, thedescent of the suspended'load is avoided by upward pull on the lever 33,as a' consequence of which the auxiliary pulley 27-isgbrought into closeengagement with the .Hy wheel@ and, is braked, thusstopping rotationofthe drum 30. H`urthermore,'when the device is used to lowera load froman elevated position without the operation of' the engine,the brakelever maybe employed inthe above described mannerto prevent a too rapiddescent.

While a specific embodiment of the invention has been illustrated anddescribed, it is to be understood that various alterations'in thedetails of construction may be madeV without departing from the spiritof the in- V- vention as indicated by the appended claims.

Having thus fully described the invention,4 what I cla-im as new anddesire to protect .by
